Lovers Lai Yiu-Fai (Leung) and Ho Po-Wing (Cheung) travel to Argentina from Hong Kong looking for adventure but soon go their separate ways. Lai is working as a doorman at a tango bar when a badly beaten Ho unexpectedly re-enters his life. Lai looks after the self-destructive Ho but his restlessness causes him to desert Lai once again, even as Lai befriends young Taiwanese Chang (Chen). After Chang returns to Taipei, Lai begins to suffer from depression and serious homesickness, as well as still worrying about Ho. Edgy visuals and playful performances bely a serious nature. Chinese and Spanish with subtitles.
